Anomalous scattering with soft X-ray radiation creates new possibilities in phasing for macromolecular crystallography. The heart of a Cr-Phasing HomeLab is any Rigaku rotating anode generator with a chromium anode.

All Rigaku rotating anode generators can be equipped with chromium (Cr) targets to provide the foundation for a Cr-Phasing HomeLab. All Cr-Phasing HomeLabs use the same optics and choice of large aperture detector.

VariMax™ Cr optics maximize the beam produced by the Rigaku generators and deliver it exactly where it is needed: on the crystal. Incident and exit helium beam paths reduce air absorption and reduce background scatter. Since Cr radiation expands the diffraction pattern relative to Cu, a large aperture detector, such as the Rigaku R-AXIS IV++ or R-AXIS HTC, is recommended.
